Sidra is an instance of the Lovelace AI program usually intended for long haul ships. After the death of her previous installation (with whom Jenks was in love) on the Wayfarer, she leaves the ship in a body kit in order to not further disturb the crew with her presence.

She chooses the name 'Sidra' (an unremarkable earthen name) to not arouse suspicious.

Sidra lives with Pepper and Blue on Port Coriol .
